* Fix crash in CameraRecoilComponent from NaN values
Doesn't proceed with camera shake if either component of recoil is NaN.
* Log NaN recoil value in CameraRecoilComponent
* Fix ExplosionHelper passing NaN recoil values when exploding from hand
With other commits CameraRecoilComponent now won't crash from NaN recoil values. Still want to fix this so explosions shake the camera. Just sets a value slightly greater than 0.0 for distance if it is (0.0, 0.0)
